Unless something has changed "orange" comes in Epsom and "potiron" comes in Clemence. Both have the same bright orange strap (too bright for the potiron IMHO).
Hmmm, things must have changed...I tried on an orange clemence evelyne on Madison ave on Friday. It def exists
If you are considering a bright color in epsom, go for cyclamen...that color gives me goosebumps.......
